M/s. The India Cements Ltd., Sankarnagar Narnamalpuram village Tirunelveli Taluka Tirunelveli District Executive Summary of 48 MW Captive Thermal Power Plant Prepared by Enviro Care India Pvt. Ltd., 43, 2nd Street, Harveey Nagar, – Madurai 621 056 Executive Summary of EIA for proposed Captive Power Plant, The India Cements Ltd., Sankar Nagar 1 EXECUTIVE SUMMARY INTRODCUTION M/s.India Cements Limited (ICL) a pioneer in cement manufacturing process, is involved in the captive power generation through the Coromandel Electric Company Limited (CECL) - a natural gas based power plant at Ramanathapuram district and wind turbines at Palladam and Thevarkulam. Still the power requirements of ICL plants are more than the present captive power generation arising from CECL and wind turbines. In order to fill the gap, ICL is proposed to set up a coal based power plant with the capacity of 48MW with in the existing premises of ICL Sankar Nagar cement manufacturing unit. According to guidelines of the Ministry of Environment and Forest the present scenario of all aspects of environment within 10km radius of the study area of proposed power plant have been evaluated and incorporated in the Environmental Impact Assessment report. The objectives of the study are: To establish the present environmental scenario To prepare a detailed action plan for implementation of mitigative measures. To suggest preventive-and mitigative measures to minimize adverse impacts and to maximize beneficial impacts. To suggest a monitoring programme to evaluate the effectiveness of mitigative measures To implement the environmental protective measures to eliminate the negative impacts. To suggest the formation of a core group responsible for implementation of environmental control and protective measures and monitoring of such implementation. To suggest a feedback mechanism enabling to make mid course corrections To prepare a capital cost for Environmental monitoring and Environmental Management Plan.

Hence the total water consumption for ICL and proposed power project will be well with in the permitted quantity. Raw material requirement Coal / Petcoke TPH TPD If Indian coal only ~55.0 ~1320.0 If imported coal only ~22.0 ~528.0 If pet coke and Indian coal (@ 50% + ~25.0 ~600.0 50%) If pet coke and Indian coal (@ 50% + ~28.0 ~672.0 50%) limestone consumption will be Power requirement Out of the total power generation of 48 MW from the proposed power plant, the plant auxiliaries will consume 5.0 MW, and 24.0 MW will be supplied to ICL Sankar Nagar unit and the rest of 19.0 MW will be wheeled to the other ICL plants located in Tamil Nadu. Process description The proposed captive thermal power plant will be based on Circulating Fluidized Bed Combustion (CFBC) technology capable of burning a wide variety of solid fuels viz Imported / Indigenous coal. DESCRIPTION OF THE ENVIRONMENT For base-line data collection, an area covering 10 km radius from the proposed captive thermal power project site as the centre has been considered as per EIA guidelines published by the MoEF, Govt. of India. The study has been carried out for the period of February to April 2010.
